Answers for Do the scientific laws in Biology were made forever? Or is change accepted?

True laws are universal in space and time, which means that they are valid forever. However, human knowledge is unable to assert that any law is really true. We and science can only say that the truth of some law, including those of Biology, is a hypothesis we currently support. So, scientific knowledge is forever... hypothetical. Although truth actually exists, we can never say that we are certain of knowing it.
